Does if prompt for a log in?
I am running a PC with Vista Ultimate 64bit edition, a laptop with vista premium and a 1TB buffalo harddrive. The whole network was working fine, until recently when I moved the sky router that everything runs from, from one side of my living room to the other. Now I can access the external hard drive from the PC and access all files on the laptop from the PC, but the laptop cannot access the PC or the external hard drive. I have checked all user permissions and sharing options and can't for the life of me find the problem. No settings have been changed from when it was working! Does anyone have any suggestions?
